Product Overview
The 3G3MX2-AB004-V2 is the 0.4 kW step in the MX2 V2 single-phase 200V class — sitting between the 0.2 kW AB002 and the 0.75 kW AB007. The 'AB' suffix identifies single-phase 200V input; the 'A2' suffix is three-phase 200V, and the 'A4' suffix is three-phase 400V. Mixing these up is a common procurement error: the AB models can only accept single-phase input. The 0.4 kW / 0.5 HP rating covers a lot of OEM machinery: small conveyors, dosing pumps, peristaltic pumps, agitators, small fans, and metering skids. The single-phase 200-240V input is the practical sweet spot for light-commercial and small industrial environments in the EU, UK, Australia, and most of Asia — anywhere you only have 230V single-phase available, not three-phase. On the input side, the drive accepts 1-phase 200-240V at 50/60 Hz. It then rectifies to DC internally and synthesises a 3-phase output to drive a standard 3-phase induction motor. This is the standard 'single-phase to 3-phase VFD' topology. The drive can NOT power a single-phase motor — only 3-phase induction motors work with VFDs in this configuration. Sensorless vector control gives the same benefits as on larger MX2 models: better low-speed torque, more stable speed under load changes. The V2 firmware adds improved auto-tune that handles most small motors without manual parameter entry. Common use: OEM packaging machine retrofit where the line was originally fixed-speed and the customer wants speed control. The AB004 replaces a contactor + thermal overload setup and gives the operator a 0-60Hz potentiometer knob on the front of the cabinet, with no need to pull in a three-phase supply.

FAQ for 3G3MX2-AB004-V2
Can I run a 3-phase motor from single-phase 230V with the AB004-V2?
Yes — that's the AB004-V2's main job. It takes single-phase 200-240V in and synthesises 3-phase output to drive a standard 3-phase induction motor. The motor must be 3-phase; you cannot run a single-phase motor from a VFD.
What's the difference between AB004-V2 and AB004 (non-V2)?
V2 is the 2024 firmware revision. Improvements include faster auto-tune, better low-speed torque stability, and updated Modbus register mapping. The hardware is mechanically identical. New installations should use V2; if you have a non-V2 in the field, you can usually replace it with V2 and reuse the parameter file.
Do I need a braking resistor with the AB004-V2?
For most 0.4kW loads, no — the inertia is low and the built-in brake transistor handles typical decel rates. For high-inertia loads or fast-stop applications, add an external 3G3AX-RB1500 or equivalent resistor (the same one used on the A4110-V2).
What size motor can the AB004-V2 drive?
0.4kW (0.5HP) in normal duty, 0.55kW in light duty. The drive can supply a 0.5HP motor at constant torque or a 0.75HP motor at variable torque (centrifugal pump or fan). Don't run a 1HP motor on this drive — the current limit will trip the drive within seconds.
